摘要
采用水解法制备了羟铂酸(H2Pt(OH)6),通过化学分析、XRD、TG/DSC、XPS、FTIR等技术对羟铂酸的组成和结构进行了分析和表征。通过化学分析检测所制备的化合物中铂的含量为65.07%,与H2Pt(OH)6中的铂的理论含量65.22%相比,两者相符较好,结合XRD衍射,表明所制备的化合物为H2Pt(OH)6,属单斜晶系;通过TG/DSC,XPS,FTIR等检测技术,推断H2Pt(OH)6为Pt(Ⅳ)与配位水和羟基配位基团形成的络合物,具有八面体空间结构。
H_2Pt(OH)_6 was prepared by hydrolysis method, and characterized by chemical analyses, XRD, TG/DSC, XPS and FTIR. The measured contents of Pt existing in the H_2Pt(OH)_6 is equal to 65.07%, by means of chemical analyses, which agreed with the theoretical calculation (65.22%). XRD result shows that H_2Pt(OH)_6 crystal is in monoclinic system with C2/c space group. The results of the TG/DSC, XPS and FTIR test indicate that H_2Pt(OH)_6 is a octahedron-structured complex involving H_2O and OH ligands.
